Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

New Blog: Introducing Ray Tracing Position Fetch Extension
On April 27, 2023 the VulkanĀ® Ray Tracing TSG released the VK_KHR_ray_tracing_position_fetch extension, which exposes the ability to fetch vertex positions from an acceleration structure hit when tracing rays. The SPIR-V SPV_KHR_ray_tracing_position_fetch and GLSL GL_EXT_ray_tracing_position_fetch extensions have also been released to provide SPIR-V and GLSL support for this functionality.
- Where can I find and what is with there being practically no documentation for GL_EXT_spirv_intrinsics and spirv_by_reference?
-
Thoughts?
You can also have general extensions that are only supported on some hardware, for instance NVIDIA supports all of these extensions on OpenGL that add support for Vulkan's thread subgroup operations while AMD only supports these extensions and a few others that add support for similar features to the extension that NVIDIA supports, but with way more restrictions.

Is there any way to index an array of bindless textures based on gl_InstanceID?
I don't think there's away. For Vulkan, there's GL_EXT_nonuniform_qualifier which allows you to index with gl_InstanceIndex but AFAIK it's not available for OpenGL.
-
Drawing multiple separate textures in one draw call
AMD hardware works a little differently, and for that you have to write a waterfall loop with subgroup instructions to get the correct behavior (since GL_EXT_nonuniform_qualifier doesn't exist in OpenGL GLSL). The loop might look like this (you would use it the same way as NonUniformEXT in Vulkan GLSL).

PS: I've been building a toolkit on top of that, that I use for a file explorer/editor, but it's not stable yet, still many little design points to think more thoroughly.

So you want to write a GUI framework
https://github.com/jeffhain/jolikit/blob/master/README-BWD.m...
It's not in version 1.0 yet, but should still remain quite stable (or even frozen, or... dead ;) in the future. Before doing so I'm waiting to finish the toolkit I'm building on top of it (which might involve also finishing the apps I'm building on top of the toolkit ;).
